men vs. women - spending habits

As a graphic designer it is important to keep yourself up to date about new techniques and designs. I really like to study graphics of other designers to get a bigger picture of the infographic world and also to collect new ideas. This way I can adapt things I really like about the work of others and maybe include some features in my next graphics.

I found the following infographic which compares spending habits of women with spending habits of men on this interesting website. Besides the comparison of spending habits it also includes average income and the top five items men and women typically spend their money on.

I really like the fact how this infographic visualizes the comparison between men and women as a battle. There is a clear hierarchy which leads the user from the top of the graphic to the end. Also the images and colors are used very efficiently and always keep clear the contrast between men and women. This idea of "battle" and creating an intense contrast in order to compare two elements are new for me and I hope I can use them in one of my next infographics. What do you think about this work? Can you also still learn from studying the graphics of others?
